Logging, Error Reporting & Diagnostics
Build a logging and error-reporting layer so you can diagnose problems in extensions running on real users' machines.
You Cannot Watch Every Console
Once your extension ships, you cannot open dev tools on every user's browser. A deliberate logging and error-reporting strategy is how you learn what is going wrong in the wild.
A Central Log Function
Wrap logging in one function so you can change behavior in a single place, add timestamps, and silence output in production.
function log(level, msg) {
console[level]('[MyExt] ' + new Date().toISOString() + ' ' + msg)
